I am 31 wks pregnant and have been bleeding and passing clots, big clots this has happened 3x. The first time I went to the ER by ambulance b/c I thought I was having a placents abruption. I had never seen so much blood the hospital ran all kinds of test and said they couldn't see anything not even on the ultra sound that would support a placenta preva. The 2nd and 3rd time I just drove myself to the ER and still nothing. I have been placed on total bedrest and told I will probably deliver before my 35th week... I know this sounds horrible but im at the point that if she is gona come early then come on b/c I feel like im a prisoner of my own body and im scared that I will be in the car and she'll just decide to come before I can get to the hospital and for this I have cancelled all appts but its like if I do nothing for the next 3-4 wks I could lose so much stuff. Has this ever happened to anybody? And when did you deliver? Did they ever find out afterwards what was going on?
